Abstract
An organic electroluminescent material is disclosed. The organic electroluminescent material is novel dehydro-fused-ring compounds with a structure of B(A), which may be used as charge transporting materials, charge injection materials, and the like in organic electroluminescent devices. Such novel compounds have very deep LUMO energy level, so they are excellent electron acceptor materials and charge transfer materials. They also have the potential to be excellent hole injection materials and p-dopant materials, and have broad industrial application prospects. An electroluminescent device and a compound formulation are also disclosed.
